Talked with a ski patrolman yesterday who said that closing is scheduled for April 17, with Seattle Ridge and bowls closing April 3.
IMO it is possible that the bowls will be open after April 3 and that the Warm Sprigs side might extend to April 24, depending on snow coverage and conditions.
Some years the April skiing is quite good, while other years it gets pretty sloppy.
